ToaZZ whom it may concern:

. -Be it known that I, 1 LAWRENCE W. DAUGHENBAUGH, a citizen of the 'United States,'residing atAltoona, in the countyof .Blainand State of 5 Pennsylvania, have 1nvented certain new and useful Improvements in EndDoorsfor RailwayCars, of which the following is a specification.

My invention-relates to-doors of metal construction and has for one of its primary objects to provide a metal door structure, thatis, a .dooriand; its frame, suitable for the end of a:.railway box car, particularly a sheet metal car end, which will be strong, durable, inexpensive to manufacture and waterproof, and 'which for theseand other reasons may beadvantageously employed in this or analogous situations.

Af'further object of r the invention is to provide in a .door construction for sheet metal car ends, afdoor" frame or supporting and guiding wmeans for the sliding door which is so constructed. that it will-not be distorted so asto prevent' thedoor from being opened or closed, or soas to make the movements of the doordifiicult, in case the sheet metal structure to which it is attached becomessbent ordeflected, for example, by

theinterior thrusts and pressures of'the cargo.

The invention consists of the several devices; arrangements and combinations hereinafter described and. claimed for carrying out the above stated objects. .LThe in-ventionis illustrated, in a preferred embodiment, in the accompanying draw- .lngs where1nticalsection oniline 33 of Fig. 1; Fig. 4,

' in F ig. 5; "Figsj 7 and "8, perspective views of the clips for receiving. and engagingthe door when open-position; Fig. 9, aview,

in elevation, of a modified construction in which the door is corrugated; Figs. 10 and 11, sectional views taken respectively on lines l010and1111 of Fig. 9; Fig. 12,

a view similar to 'Fi 1 showing the pre- Fig-.- 16, a view, in perspective, ofa channelshapedmember which fits overthe forward edge of the door shown in Figs. 12 to 14, inclusive.

' Like characters of reference designate like I parts in the several figures of the drawings.

Referring first to Figs. 1 to 8 inclusive, 25 designates a sheet-metal structure, for example, a sheet metal car end, which is shown as formed with pressed stiffening ribs or corrugations 26 and with a door opening 27. Arranged inthe door opening 27 is a, preferably cast, door frame 28 provided with a flange 29 overlapping the portions of the end sheet adjacent the door opening and secured thereto by rivets 30. As, in the construction shown, the door opening interrupts the corrugations 26, the flangef29 of the door frame .is fluted or corwhich it is attached. The upper member of the door frame is formed with a channelshaped web 31 providing a guideway for the upper edge of the door 32. Preferably the web 31 is carried continuously around one end or forward side of the door frame, as indicated at 33, so as to provide a recess for the forward edge of the door. The guideway for the lower edge ofthe door is provided with a strip 34 (Fig. 5) secured to thelower member of the door" frame by rivets 35 and formed with a channel-shaped part 36, the channel 37 of which is preferrugated so as to closely fit the structure to ably open at opposite ends. Preferably the element 34 is longer than the width of the door so that it supports the. door when in open position, the rearwardly projecting part of the element being supported by a bracket 38 (Fig. 6) secured to the end sheet 25.

The door 32 slides in the guideways 31,

30 rial No. 786,453, filed'Au-gust 25, 1913, of

36 and'is preferably formed of sheet metal adapted to receive the upper edge of the door when opened. The door is therefore firmly supported and held in its open position-which is essential in order that it should not be distorted or otherwise injured by the vibration of the car when in motion. It often happens that through carelessness the end door of a railway car is left open, while the train is in motion.

Y The door frame is preferably provided with a pivoted. gravity latch adapted to engage in a recess 46 formed in the door, when'thedoor-is closed, and also to stand in front of the forward edge of the door when the latter is open. The latch and the 'parts'operatively associated therewith are not claimed herein asthey form the subject matter of my pending application Sewhichthe present application is a division.

In the construction above described, the

interlocked engagement of the door,- when closed, with the door frame, will, under ordinary circumstances, effectively prevent water from getting into the car through the door structure. However,-in order to make this perfectly certain I preferably form the lower member. of the door frame with one or more drainage channels 47 which open into thechannel 37 in which the lower edge of the door slides so that if by any chance w'ateri should get in between the door and the door frame it will be intercepted by these channels and drained out. I

The construction shown in Figs. 9 to 11 inclusive is essentially the same as that just described except that the door 32*? is formed with a.- plurality of pressed out ribs or corrugations 32? which preferably run vertically of the door. This construction makes it advisable to employa different form of locking device, which is shown as consisting of a pivoted latch 45, but will not be particularly described as, under therequirement for division of the parent application above referred to, the locking, means forms aseparate invention from the door construction per se.

It will be seen that with a doorframe constructed as above described the end sheetis are. taken up by the door frame and transmitted to the corrugations on the other side. By forming the door with corrugations, as shown in Figs. 9 to 11 inclusive, the door will be made very stiff and strong. The flange 29 on the door frame preferably lies back of the edge of the end sheet so that there is little or no likelihood that water will work into the car at this place.

In the preferred construction shown in Figs. 12 to 16 inclusive, 50 designates a'sheet metal car end having a door opening 51 cut therein and formed with corrugations 52, which terminate a short distancefrom the edge of the door opening so as to provide a flat surface 53 adjacent thereto. The door frame 54 is preferably a malleable iron casting and is arranged within the opening so that the flange 55 may be secured to the in ner face of the flat surface 53 by means of rivets 56. 'The door 57 is supported in the channel-shaped portion 58 of a guide strip 59, similar to the one shown in Fig. 5, and which is secured to the lower member of the door frame by rivets 60. Secured to the forward side of the door frame is a channel shaped member 61, the channel portion 62 of which fitsover the forward edge of the door when the latter is in closed position. The channel portion 62 is formed at its lower end with an extension 63 which closes the opening in the forward end of the .lower guideway 58, and at its upper end fits within an enlarged portion 64 of theiupper guideway 65 which is secured to the upper member of the door frame by rivets 66. By having the guideways overlappedin this manner .water is prevented from entering the car around theforward edge of the door. In order to prevent any water from working into the car between the guideway 65 and the upper member of the door frame, I have provided the attaching flange 67 of the guideway 65 with a downwardly extending flange 6.8 which projects into a channel 69 formed in the upper member of the door frame. The rear edge of the door is bent over soas to provide a U-shaped part 7 O which is adapted to fit over an outturned flange 71 cast on the door frame and thereby prevents water from entering the car at this point.

In addition to providing the door with a corrugation 72 which forms a recess into which the gravity lock drops when the door is in closed position, as described'in my copending application above referred to, I preferably form the door with a similar corrugation 7 3 which provides a recess adapted to serve the purpose of a handle when it is desired to manipulate the door from the inside of the car.

My invention, it will be seen, provides a door structure, the operativeness ofwhich is not affected by the possible bending or defiecti'on of the wall to which it is fitted. The end of a railway box car is subjected to very heavy thrusts and pressures due to the shift ing of the cargo when the car stops and starts. These inertia thrusts are likely to cause a deflection of the end wall, either 7 end. My construction rovides a rigid door frame, preferably a ma leable casting, which surrounds the door opening and to which the door guides are rigidly secured. If the sheet metal of the car end becomes permanently bent or is temporarily deflected, the

distortion does not throw the door guides out of alinement with each other. The door structure as a whole may shift its angular position but this will not prevent the door from being opened and closed since the relative position of the parts of the door and its guides is not changed.

Thile I have described my invention in certain preferred embodiments, it will be understood that modifications might be made without departure from the invention so that I do not wish to be understood as limiting the invention to the precise constructions, arrangements and devices shown.
